FIELD OF THE DISCLOSURE

The present disclosure relates to a pair of shoes and shoe insert covers thereof, and more particularly to slippers with a replaceable surface material.

BACKGROUND OF THE DISCLOSURE

Walking in slippers on a hot summer day can prevent feet of a person from being encased and reduce the stifling feeling.

However, some people's feet are more prone to sweating, and the sweat creates a slippery feeling between the skin of the foot sole and the insole of the slipper, resulting in skin discomfort. Worse still, the slipper may come off due to wetness and slippage, and may cause occurrence of accidents. Therefore, improvements are required.

TW Patent No. TWM550054 discloses a shoe insert (referring to FIG. 3a ) in which a massage particle 12 is adhered to the shoe insert via an adhesive surface 121. However, this invention is merely a technique of adding massage particles onto the shoe insert, and does not disclose any content about replacing a surface material of a slipper.

TW Patent No. TWM240106 discloses a slipper, in which a massage shoe insert 20 provided with massage protrusions 22 can be adhered to the insole of the slipper via a back hook surface 21 according to the demand of a user.

However, the present disclosure aims to disclose a slipper with a strap having a top end; attaching manners and main objectives of the present disclosure are different from those of the foregoing two cases, which will be described in detail below.

SUMMARY OF THE DISCLOSURE

A main objective of the present disclosure is to enable a user to choose a surface material of a pair of shoes, i.e., slippers, and shoe insert covers thereof.

Another objective of the present disclosure is to facilitate the user to easily replace the surface material of a slipper.

Still another objective of the present disclosure is to provide a comfort layer with a slit, so as to be attached to a slipper with a strap having a top end.

Yet still another objective of the present disclosure is to facilitate the user to replace the surface material of the slipper, where a fastening part is disposed on a shoe sole and is fastened to a flat sock.

A further objective of the present disclosure is to provide a shoe insert cover fixed to a shoe insert, so that the user may place the shoe insert cover into a shoe and use it to absorb the sweat, without the need to wear socks.

These and other aspects of the present disclosure will become apparent from the following description of the embodiment taken in conjunction with the following drawings and their captions, although variations and modifications therein may be affected without departing from the spirit and scope of the novel concepts of the disclosure.

The present disclosure discloses a slipper which enables a user to replace a surface material according to his/her personal use habits.

Reference is made to FIG. 1a , which shows a first embodiment of the present disclosure. A first fixed layer 1 is fixed between a sole portion 31 of a slipper 3 and a strap 33, a top end 331 of the strap 33 passes through a via hole 11 in the first fixed layer 1 to fasten the strap 33 to the sole portion 31. During assembly of the slipper 3, the sole portion 31, the first fixed layer 1, and the strap 33 are first provided; the first fixed layer 1 is fixed to the sole portion 31; and the top end 331 of the strap 33 passes through the via hole 11 in the first fixed layer 1 to fasten the strap 33 to the sole portion 31.

Referring to FIG. 1b , FIG. 1b shows the first fixed layer 1 provided with the via hole 11 through which the top end 331 of the strap 33 passes. A lower surface 15 of the first fixed layer 1 faces the sole portion 31 of the slipper 3 and is used to contact the sole portion 31 of the slipper 3. An upper surface 13 of the first fixed layer 1 faces the strap 33. When a user wears the slipper 3, the foot of the user is situated between the upper surface 13 and the strap 33.

In an embodiment, the upper surface 13 is a pile surface. When the first fixed layer 1 is disposed on the sole portion 31 of the slipper 3 (the lower surface 15 may be fixed to the sole portion 31 by a double-faced adhesive tape or an adhesive), the user can directly step on the pile upper surface 13 to wear the slipper 3.

As shown in FIGS. 1c and 1d , if the user wants to change a material which his/her foot sole contacts, a lower surface 555 (which is a hook surface in this embodiment) of a comfort layer 5 (a type of flat sock) is attached to the upper surface 13 of the first fixed layer 1, so that the lower surface 555 and the upper surface 13 (which is a pile surface in this embodiment) are fastened to each other. As shown in FIG. 1d , an attaching layer 553 and a contact layer 551 are bonded (by, for example, adhering with an adhesive or a double-faced adhesive tape, or sewing) on the lower surface 555, to form the comfort layer 5. An attaching manner is as follows: A slit 51 passes through the top end 331 of the strap 33 until a via hole 53 is fixed to the top end 331, and then the lower surface 555 and the upper surface 13 are pressed to bond together. Thus, the foot sole of the user can contact a material of the contact layer 551.

There are several differences between the structure of the present disclosure and the related art shown by a comparison between FIG. 1c and FIG. 3b . In the related art shown in FIG. 3b , connected pieces of a slipper are required to be pulled apart, so that the user can attach a massage shoe insert 20 to an insole. However, as shown in the embodiment of the present disclosure shown in FIG. 1c , without the need to pull apart or cut the strap 33, only the slit 51 is required to pass through the top end 331 of the strap 33 until the via hole 53 is fixed to the top end 331, to attach the comfort layer 5.

By comparing FIGS. 1c, 1e, and 1f , it can be learned that the difference there-between lies in the orientation of the slit 51, which may bring different effects.

In FIG. 1c , the slit 51 extends from the via hole 53 towards front ends of the toes. Such a design makes it easy to move the comfort layer 5 onto the first fixed layer 1. Moreover, after the via hole 53 is fixed to the top end 331, the comfort layer 5 is attached to the first fixed layer 1 along a direction from the front ends of the toes towards the heel. However, the slit 51 in such an orientation may appear unaesthetic. The main reason is that if the slit 51 cannot be tightly closed, the resulting relatively large space in front of the toes is easily seen by others when the user wears slippers. Consequently, a discontinuous pattern of the comfort layer 5 is obvious, thereby affecting the appearance.

In FIG. 1d , the slit 51 extends from the via hole 53 towards a lateral side of the big toe, making it easier to move the comfort layer 5 onto the first fixed layer 1. Moreover, after the via hole 53 is fixed to the top end 331, the comfort layer 5 is attached to the first fixed layer 1 along a direction from the front ends of the toes towards the heel. Compared to the orientation in FIG. 1c , the orientation of the slit 51 in FIG. 1e makes it more difficult to fix the via hole 53. The main reason is that it is first required to move the slit 51 along a direction opposite to the big toe, before moving the slit 51 to pass through the top end 331. After the top end 331 enters the slit 51, the slit 51 is moved towards the big toe until the via hole 53 is fixed to the top end 331. However, such a design alleviates the unaesthetic effect compared to that in FIG. 1c . The main reason is that the big toe of the user is located above the slit 51 (the top end 331 is mostly held between the big toe and the index toe) when the user wears the slipper. Even when the pattern of the comfort layer 5 is discontinuous as the slit 51 cannot be tightly closed, the discontinuous pattern is not easily seen such that the appearance is unaffected.

In FIG. 1f , the slit 51 extends from the via hole 53 towards a lateral side of the little toe. Such a design minimizes the adverse effect of the discontinuous pattern created by the slit 51. The slit 51 is located beneath the index toe, the middle toe, the fourth toe, and the little toe. Therefore, even when the slit 51 creates the discontinuous pattern, the discontinuous pattern is covered by the four toes when the user wears the slipper and only a small section (from the outer side of the little toe to the edge of the sole portion 31) of the pattern is exposed. The exposed section is not easily noticed by others because it is on the outmost side. Therefore, the design in FIG. 1e is unlikely to bring an unaesthetic effect as compared with the designs in FIGS. 1c and 1 e.

However, the design in FIG. 1f makes it relatively difficult to move the comfort layer 5 onto the first fixed layer 1. The main reason is that it is first required to move an opening of the slit 51 to the top end 331 before moving the top end 331 into the slit 51. However, because a space (near a side of the big toe) at the inner side of the top end 331 is smaller than a space (near a side of the index toe) at the outer side, the user needs to first properly squeeze the whole comfort layer 5 (which is a difficult operation) before successfully making the top end 331 enter the slit 51. Afterwards, the top end is moved along the slit 51 until the via hole 53 is fixed to the top end 331. Only in this way, can the comfort layer 5 be attached to the first fixed layer 1 along a direction from the front ends of the toes towards the heel, so that the foot skin of the user contacts different materials.

Reference is made to FIGS. 1g and 1h , which show another embodiment of the present disclosure. The first fixed layer 1 is provided with a hook surface on its upper surface 13, and contacts (or is fixed onto) the sole portion 31 via the lower surface 15. An object with a pile surface may be hooked by the hook surface once the two surfaces are in contact.

The comfort layer 5 in FIG. 1g has a three-tier structure, in which the upper surface 551 the user contacts may be made of cotton, wool, or polyester fiber. The lower surface 555 of the comfort layer 5 may be a pile surface, and the lower surface 555 and the upper surface 551 are fastened to each other via the attaching layer 553. When the lower surface 555 of the comfort layer 5 contacts the upper surface 13 of the first fixed layer 1, they can be fastened together. If the user wants to replace the comfort layer 5 with another comfort layer 5, the user only need to remove the comfort layer 5 from the upper surface 13 to easily implement replacement.

Referring to FIG. 1h , the comfort layer 5 has a simple design, which may have a single layer made of cotton, wool, or polyester fiber. The comfort layer 5 can be easily attached or removed by the user to/from the upper surface 13.

Referring to FIG. 1i , FIG. 1i shows a first fixed layer 1 capable of being removed from a slipper in another embodiment of the present disclosure, where the first fixed layer 1 has a via hole 11 (used to be fixed to a top end of a strap) and a slit 111 (used to enable the top end to be moved from an opening of the slit 111 to the via hole 11 and caught in the via hole). In this embodiment, an upper surface of the first fixed layer 1 is a hook surface, while in another embodiment the upper surface of the first fixed layer 1 is a pile surface. Moreover, the slit 111 extends from the via hole 11 towards front ends of the toes in this embodiment. In other embodiments, the slit 111 may extend from the via hole 11 towards the big toe; or in another embodiment, the slit 11 may extend from the via hole 11 towards the little toe.

Reference is made to FIG. 1j , which shows a manner for attaching the comfort layer 5 to the first fixed layer 1, and a corresponding structure. The first fixed layer 1 is fixed on the sole portion 31. Before attaching the comfort layer 5 to the first fixed layer 1, a non-adhesive layer 19 may be first disposed there-between, which is neither adhered to the first fixed layer 1 nor the comfort layer 5. First, the top end of the strap is moved from the opening of the slit 51 of the comfort layer 5 into the via hole 53. After confirming that the comfort layer 5 and the first fixed layer 1 are closely bonded, the non-adhesive layer 19 is drawn away, thus properly attaching the comfort layer 5 onto the first fixed layer 1. The non-adhesive layer 19 may be made from fabric, paper, or gauze; and is characterized by being adhered to neither the first fixed layer 1 nor the comfort layer 5. The non-adhesive layer 19 may also have a slit, so that the top end of the strap can be moved through it.

The embodiment shown in FIG. 1j greatly differs from the related art shown in FIG. 3b . In the related art shown in FIG. 3b , it is required to particularly pull apart the connected pieces before attaching the massage shoe insert 20 to the insole. However, by the embodiment shown in FIG. 1j , it is only required to use the non-adhesive layer. First, the non-adhesive layer is sandwiched between the first fixed layer 1 and the comfort layer 5 without sticking to them. Thus, the first fixed layer 1 and the comfort layer 5 can be arranged in positions where they are easily attached to each other. After the non-adhesive layer is drawn away, the first fixed layer 1 and the comfort layer 5 can be properly attached to each other.

Refer to FIG. 1k , which shows a detailed structure of the comfort layer 5. When the comfort layer 5 is designed in two or more tiers, these tiers may be sewn together by stitches 55. For example, the lower surface 555 and the contact layer 551 are sewn together (in the foregoing embodiment shown in FIG. 1j , there is an attaching layer 553 between the lower surface 555 and the contact layer 551), so that they are firmly fixed together.

Reference is made to FIG. 2a , which shows an embodiment of the present disclosure. A strap 33 of a slipper at the left side is covered by a second fixed layer 7, while that at the right side is not covered. In this embodiment, a first fixed layer 1 may be fixed on a sole portion 31.

In an embodiment of the present disclosure, the structure of the second fixed layer 7 is shown in FIGS. 2b and 2c . FIG. 2b shows a surface 71 of the second fixed layer 7, and FIG. 2c shows an inner surface 73 and fastening portions 75 provided thereon. The second fixed layer 7 may be fixed on the strap 33 via the fastening portions 75. The second fixed layer 7 is V-shaped, so as to match the shape of the strap 33 and be suitably fixed on the strap 33. The plurality of fastening portions 75 is arranged on designed positions (referring to FIG. 2d , which is a sectional view of FIG. 2a along line AA′), and is symmetrically distributed on the two long sides. At least one fastening portion 75 is disposed on an inner side 771 and an outer side 773 respectively. Some sections at the inner side 771 and the outer side 773 are not provided with the fastening portions 75, so that the second fixed layer 7 can be bent along the strap 33 via these sections. If the fastening portions 75 are distributed all over the inner surface 73 of the second fixed layer 7 from the inner side 771 to the outer side 773, there is insufficient space on the inner surface as the second fixed layer 7 bends along the strap 33, causing the second fixed layer 7 to be excessively pushed and squeezed and easily fell off. In addition, the second fixed layer 7 has a concave portion 79 corresponding in position to a top end of the strap 33. The concave portion 79 prevents the top end from being covered by the second fixed layer 7, thus allowing the top end to be exposed.

In the embodiment shown in FIGS. 2c and 2d , the width (a distance from the inner side 771 to the outer side 773) of the second fixed layer 7 is designed to approximate a sum of widths of a lower side, a lateral side, and an upper side of the strap 33. That is, the width of the second fixed layer 7 is greater than or equal to two times the width of the strap 33, but less than three times the width of the strap 33.

In another embodiment shown in FIGS. 2e and 2f , the second fixed layer is much wider than that in FIGS. 2c and 2d . Its width is designed to be greater than or equal to two and a half times the width of the strap 33, but less than four times the width of the strap 33. Because of the relatively large width, after the fastening portions 75 near the inner side 771 of the second fixed layer 7 are fixed to the strap 33, the fastening portions 75 near the outer side 773 are made to be twisted around the strap 33 and directly adhered onto the surface 71. In this way, when the user wears the slipper, his/her instep is in contact with the second fixed layer 7 (rather than the strap 33), so that the user can select the material (namely, the second fixed layer 7) his/her foot contacts with.

In the embodiments shown in FIGS. 2b to 2f , the fastening portions 75 are adhesive and can be adhered to a contacted material, which may be a double-faced adhesive tape, an adhesive having a repeatable adhesion capacity, or the like. In an embodiment shown in FIG. 2g , the fastening portions 75 that are near the inner side 771 and the outer side 773 are made of different materials. For example, when the fastening portions 75 near the inner side 771 have a Velcro® hook surface the fastening portions 75 near the outer side 773 can have a pile surface. Thus, the fastening portions 75 of two different textures can be fastened together once in contact. Vice versa, when the fastening portions 75 near the inner side 771 have a Velcro pile surface, the fastening portions 75 near the outer side 773 have a hook surface.

In an embodiment shown in FIG. 2h , the fastening portions 75 are made of different materials. For example, when the fastening portion 75 adhered to the strap 33 has a Velcro pile surface, the fastening portion 75 (not shown in the figure) adhered to the second fixed layer 7 has a hook surface. Thus, the fastening portions 75 of two different textures can be fastened together once in contact. Moreover, if the fastening portion 75 adhered to the strap 33 has a pile surface, the user can directly wear the slipper because the material of the pile surface is soft and comfortable, without the need to adhere any material to the strap, avoiding affecting the original function of the strap. Alternatively, if the fastening portion 75 adhered to the strap 33 has a Velcro hook surface, provided that the fastening portion 75 (not shown in the figure) adhered to the second fixed layer 7 has a pile surface or the material of the second fixed layer 7 can be caught on by the Velcro hook surface (for example, the second fixed layer 7 has a pile surface), the second fixed layer 7 can be fixed on the strap 33 once the hook surface and the pile surface are in contact.

In an embodiment shown in FIGS. 4a and 4b , a front side and a back side of a flat sock 91 (which is the aforementioned comfort layer) are respectively shown, and a sock body 911 and a joining portion 913 are fixed together. The sock body 911 has a front side 911 a and a back side 911 b as shown in FIG. 4b ), and is made of a sweat-absorbing material which may be one or a combination of various materials such as cotton, polyester fiber, elastomer, and the like. The joining portion 913 is presented in different forms in different embodiments, and therefore is shown by dotted lines.

FIGS. 4c and 4d are respectively a right view and a left view of the flat sock 91. As shown in FIGS. 4c and 4d , the sock body 911 has a front side 911 a and a back side 911 b which are fixed together with a joining portion 913. FIGS. 4e and 4f are respectively a front view and a back view of the flat sock 91. As shown in FIGS. 4e and 4f , the sock body 911 has a front side 911 a and a back side 911 b which are fixed together with a joining portion 913.

FIG. 4g is a perspective view of this embodiment. The sock body 911 has a front side 911 a (and a back side 911 b), and is connected to the joining portion 913 in this embodiment. The flat sock 91 is used to be adhered to an insole 933 of a shoe 93, and reference is made to an embodiment shown in FIGS. 4h to 4i . FIG. 4h shows a status in which the flat sock 91 does not contact the shoe 93. The shoe 93 has an upper 931, the insole 933, and a shoe sole 935. The upper 931 and the shoe sole 935 are fastened to each other, and the insole 933 is arranged between the upper 931 and the shoe sole 935. When a user wears the shoe 93, his/her instep is in contact with the upper 931, and the foot sole is in contact with the insole 933. Whereas when the user steps on the ground, the shoe sole 935 lies between the insole 933 and the ground. FIG. 4i shows a status in which the flat sock 91 is attached to the insole 933 of the shoe 93 and covers the insole 933, but the joining portion 913 has not yet been fixed thereon. FIG. 4j shows a status in which the joining portion 913 is fixed to the shoe 93, and the flat sock 91 completely covers the insole 933. In this embodiment, the joining portion 913 is fixed to the shoe sole 935, while in other embodiments the joining portion 913 may be fixed to the insole 933. When the flat sock 91 completely covers the insole 933 and the user wears the shoe 93, the flat sock 91 lies between the foot sole of the user and the insole 933.

Viewed from an arrow AA′ in FIG. 4j , a schematic diagram is shown in FIG. 4k . The back side 911 b of the flat sock 91 is attached to the insole 933 of the shoe 93, so that the flat sock 91 lies between the upper 931 and the shoe sole 935, and is fastened to the shoe sole 935 via the joining portion 913. When the user wears the shoe 93 and steps on the front side 911 a of the flat sock 91, the back side 911 b of the flat sock 91 can be firmly fixed on the insole 933, without causing a slide.

FIG. 5a is a schematic diagram showing that the flat sock 91 is fastened to the shoe sole 935 (by a fastening region B2) of the shoe 93 via the joining portion 913 (by a fastening region B1), so that the back side 911 b of the flat sock 91 is attached onto the insole 933. There are many manners in which the joining portion 913 is fastened to the shoe sole 935, and various embodiments are listed below.
